Formaldehyde (FA) can cause severe central nervous system impairment. But, there are only a few studies about biochemical and histopathological changes of frontal cortex and hippocampal tissue caused by FA toxicity. The aim of our study was to investigate these changes occurring after chronic formaldehyde toxicity in frontal cortex and hippocampal tissues,(More)
The hippocampal formation is a complex region of the brain related to memory and learning. The purpose of the present study was to determine whether exposure of neonatal rats to formaldehyde (FA) had either early or delayed effects on the numbers of granule cells in the dentate gyrus (DG). After birth, the neonatal male Wistar rats were exposed throughout a(More)
OBJECTIVE The aim of this experimental study was to evaluate the oxidant/antioxidant status and lipid peroxidation in the heart of rats exposed to formaldehyde (FA) inhalation for four weeks (subacute) or 13 weeks (subchronic) continuously. METHODS AND RESULTS Sixty Wistar albino rats were divided into six groups randomly (ten in each group). The first(More)
Omega-3 (omega-3) is an essential fatty acid (EFA) found in large amounts in fish oil. It contains eicosapentaenoic acid and docosahexaenoic acid (DHA). DHA is one of the building structures of membrane phospholipids of brain and necessary for continuity of neuronal functions. Evidences support the hypothesis that schizophrenia may be the result of(More)
OBJECTIVE Sepsis and ensuing multiorgan failure continue to be the major causes of mortality in intensive care units. Nuclear factor (NF)-kappaB activation is supposed to be one of the targets in the treatment of sepsis. We studied the effectiveness of caffeic phenethyl ester (CAPE), a known NF-kappaB inhibitor, in cecal ligation and puncture (CLP)-induced(More)
The level of trace elements such as Zn, Cu and Fe in testicular tissue is an indication of the condition of the tissue as these elements take over important tasks. Zinc and copper are the prosthetic groups of several metalloenzymes including superoxide dismutase (SOD) which is an important antioxidant enzyme in the cellular protection from reactive oxygen(More)
Reactive oxygen species (ROS) have been implicated in the pathogenesis of cerebral injury after ischemia-reperfusion (I/R). Fish n-3 essential fatty acids (EFA), contain eicosapentaenoic acids (EPA) and docosahexoenoic acids (DHA), exhibit antioxidant properties. DHA is an important component of brain membrane phospholipids and is necessary for the(More)
The goal of this study was to examine the neuroprotective effect of ebselen against intracerebroventricular streptozotocin (ICV-STZ)-induced oxidative stress and neuronal apoptosis in rat brain. A total of 30 adult male Sprague-Dawley rats were randomly divided into 3 groups of 10 animals each: control, ICV-STZ, and ICV-STZ treated with ebselen. The ICV-STZ(More)
One parameter which might provide an insight into the underlying mechanism of the effect of formaldehyde (FA) inhalation on testicular tissue, is the assessment of heat shock protein 70 (Hsp70), which increases promptly in cells exposed to stress caused by chemical toxicity. Thus, following subchronic exposure at cytotoxic concentrations, we studied the(More)
Vertebral arteries form the basilar artery at the pontobulbar junction. The vertebral artery may have dominancy in one of them. The branches of basilar arteries supply blood for the vestibular nuclei and its connections. Vertigo is seen generally in the upper middle aged patients. Vertigo can be observed in dolichoectasia of basilar artery such as(More)
